Some of the investment approaches discussed in Investment Gurus involve reviewing the available information concerning a company, its industry, and the overall economy and making accurate value judgments before the rest of the market figures out the same thing (and prices change accordingly!). Other approaches do not rely spe- cifically on faster reactions to significant news developments, but do rely on high quality financial data to permit careful analysis of in- trinsic value or likely earnings acceleration. In the end, we discover that achieving consistent profit requires a wise understanding of risk and the ability to choose exposure to risk prudently. Any individual seeking greater success in the market must understand at the outset what could go wrong (as well as the theories of how to make things go right).
